Passage through the strait Late on 28February, outgoing traffic through the Strait of Hormuz was heavy, while incoming traffic was light. At least three tankers were struck near the strait, including one off Oman that was set ablaze. At least 17oil tankers continued travelling through the strait. On 1and 2March, no ships appeared in the strait.
Houthi-controlled Yemen announced on 28February that it
would resume attacks on Israel and commercial ships in the Red Sea, forcing Suez Canal traffic to be rerouted around Africa's
Cape of Good Hope. This added weeks to transit times and increased shipping costs. The crisis disrupted global energy supplies and stranded tankers in the Persian Gulf.
Cruise ships reduced activity in the Persian Gulf and stopped using the strait, stranding 15,000passengers on at least six major cruise ships: Saudi-based cruise line Aroya Cruises' eponymous
Aroya; two ships owned by
Celestyal Cruises,
Celestyal Discovery and
Celestyal Journey;
MSCEuribia of
MSCCruises; and two
TUICruises ships,
Mein Schiff4 and
Mein Schiff5. On 15 March, an Iranian commander said that Iran would continue to use the Strait of Hormuz as a pressure point. Several ships have passed the strait during the conflict, mostly petroleum ships bound for China and India. On 16 March, a Pakistani oil tanker crossed the Strait of Hormuz with Iranian permission. Iran set up its own shipping channel, north of
Larak Island rather than the main channel south of the island. One ship paid $2 million to use Iran's channel. Unaffected by the war, 20 Iranian vessels per day used the Iranian port of
Bandar Abbas. On 26 March, Malaysia said that Iran allowed its ships to pass through the strait. According to
Lloyd's List, payments were being assessed by the
Iranian Revolutionary Guards in
Chinese yuan. On 3 April, a French ship crossed the Strait of Hormuz. On 9 April, there was no sign that a recent agreement to lift the Iranian blockade of Strait of Hormuz was being implemented, with ships once again being prevented from passing through the strait.
Abu Dhabi National Oil Company CEO
Sultan Al Jaber said on that day that the strait was still not open, despite the
Iran war ceasefire, because Iran is restricting and conditioning traffic. He added that 230 loaded oil tankers are waiting inside the Gulf. Around 18 April, during a brief time window where both Iran and United States claimed the Strait was open, all six cruise ships sailed from the Persian Gulf through the Strait, into the Arabian Sea and beyond, resuming their commercial schedule elsewhere. On 19 April, Mohammad Rezaei-Kouchi, head of the Iranian parliament’s construction committee, said that the Iranian parliament was planning to pass a law that boats from "hostile" countries cannot pass the Strait, and that all others will need to pay tolls. By 20 April, traffic through the Strait had dropped sharply again, as on 1 March. The
International Maritime Organization reported on 21 April that about 20,000 mariners and 2,000 ships remained stranded in the Persian Gulf because of the closure. While passage through the strait is curtailed, small boat, particularly speedboat, commercial traffic across the strait continues.
Global economy petrol station in
Thailand closing with a sign stating "out of diesel" on 22 March 2026 as the country was hit by a fuel shortage due to its reliance on shipping via the Strait of Hormuz The restriction of shipments by more than 90% (around 10 million barrels per day of oil production) raised energy and agricultural input costs worldwide. The spike in prices is especially problematic in Asia, where major importers like China and India could face supply shortages and price volatility. Natural gas prices in Europe also surged, rising from €30/MWh the past week, to €46/MWh on Monday, 2 March, peaking above €60/MWh on Tuesday, 3 March (nearly double from previous week), before decreasing again to €48/MWh on Wednesday, 4 March. The crisis has been described as the largest disruption to the energy supply since the
1970s oil crises and as the largest in the history of the global oil market. Analysts from institutions like
Barclays and
Goldman Sachs highlighted risks of sustained high oil prices if the strait is restricted over a longer period.
OPEC+ pledged to increase oil output by 206,000 barrels per day to mitigate shortages. On 4 March,
Pakistan, a country reliant on imported oil that was looking for alternative shipment routes due to the closure, officially requested that Saudi Arabia reroute oil supplies through
port of Yanbu on the Red Sea, with Saudi Arabia providing assurances and arranging at least one crude shipment to bypass the closed strait. Saudi authorities also
diverted some of their own crude exports via
Yanbu to reduce the impact. On 3 March, Iraq started shutting down operations at the
Rumaila oil field due to a lack of storage space, as tankers were unable to leave the strait. On 6 March, Qatari Energy Minister
Saad Sherida al-Kaabi warned that if the war continues, other Gulf energy producers may be forced to halt exports and declare
force majeure, and that "this will bring down economies of the world".
QatarEnergy had already stopped gas production on 2 March and declared
force majeure on gas contracts on 4 March. On 7 March, the
Kuwait Petroleum Corporation declared
force majeure and announced that it would be cutting its oil production. Bahrain's
Bapco Energies declared
force majeure The missing oil is mostly
Medium and Heavy grades, which some Asian refineries depend on and cannot easily switch to lighter grades. Oil exports from the region were 25million barrels per day before the war, dropping 60% to around 10million by 15 March. Iraq declared
force majeure on "all oilfields developed by foreign oil companies" on 17 March. On 8 March, crude oil prices surpassed US$100 per barrel for the first time in four years, since the
2022 Russian invasion of Ukraine, and reached a high of $126. The price surge was faster than during any other conflict in recent history, such as the Ukraine war, the
Gulf War, or the
Iraq War. On 11 March, the 32
International Energy Agency member states unanimously agreed to release 400 million barrels of oil, representing about four days worth of global consumption, from their emergency reserves. The crisis has also led to a slight increase in the number of ships traversing the
Panama Canal. In the second week of March, California's gasoline prices exceeded $5 per gallon due to the United States' conflict with Iran. On 19 March, Dubai crude oil prices reached US$166, their highest on record. On 23 March, in response to President Trump's comments on US–Iranian negotiations, Brent crude prices fell from US$114 to US$102 per barrel. On 27 March, Brent crude increased to US$114 per barrel, after negotiations did not produce a ceasefire and the IRGC declared the strait to be closed.
Industry The US defense industry is affected by "near total" disruption of critical minerals supply, in particular
sulfur, through the strait. In face of sulfuric acid scarcity, China has banned exports impacting among other things
copper production in Chile which imported sulfuric acid as consumable.
Aluminum prices experienced a slight increase, as the Gulf states account of 20% of raw aluminum exports and 8% of aluminum production. The Gulf region also produces nearly half of the world's
urea and 30% of
ammonia, with about one-third of the world's
fertilizer passing through the strait. Unlike oil, the fertilizer sector does not have internationally coordinated strategic reserves, making supply disruptions more difficult to manage. It is estimated that global fertilizer prices could average 15–20% higher during the first half of 2026 if the crisis continues. In response, the Iranian defense council threatened to lay mines throughout the Persian Gulf. On 23 March, Trump postponed the ultimatum, citing "very good and productive conversations" with Iran. On 30 March, Trump threatened to strike Iranian energy infrastructure if they do not reopen the strait. On 31 March, Trump told countries that were having trouble getting fuel due to the closure to fend for themselves, saying that the US would not help them. On 4 April, Trump reasserted the ultimatum, giving Iran another 48 hours to open the Strait or "face hell." Trump later extended the ultimatum by one day, until 7 April at 8:00 p.m. Eastern Time. Iran denied having conducted any negotiations with Trump. and it also suggested that the negotiations were an effort to sow discord within Iran. At the same time, the Iranian Foreign Ministry acknowledged that it was reviewing a proposal it received from the United States. According to an analysis in
Iran International, Trump's statements succeeding in lowering oil prices while also "fracturing" the Iranian regime. On 7 April, US Ambassador to the United Nations
Mike Waltz said that "no country gets to hold the world hostage for leverage just because they happen to sit next to a strait." On 7 March, the
Indian Government proposed to deploy the
Indian Navy to safeguard the oil supplies it receives. On 9 March, French president
Emmanuel Macron announced that France and several other states are setting up a "purely defensive, purely support" escort mission for merchant ships transiting the strait, in the framework of
Operation Aspides, and that France is sending a dozen ships to the wider Middle East. The
French Navy vowed to send two frigates to escort vessels through the strait. As of 10March, Britain, along with Germany and Italy, are working to support commercial shipping through the Strait of Hormuz. Also on that day, US
chairman of the Joint Chiefs of Staff General
Dan Caine said that the USmilitary was looking at a "range of options" for restoring tanker traffic. The US sent the
31st Marine Expeditionary Unit to the region, where they are expected to try to secure the Strait of Hormuz. is expected to lead maritime security operations in the Strait of Hormuz. On 11March, the
G7 nations agreed to look into the possibility of escorting ships through the strait. US Energy Secretary
Chris Wright on 12March said that the USNavy may be able to start escorting ships through the strait by the end of March, with the military still focused on "destroying Iran's offensive capabilities and the manufacturing industry that supplies their offensive capabilities." On 15 March, British energy secretary
Ed Miliband said that the UK was considering "any options" to secure the Strait of Hormuz. Later that day, British prime minister
Keir Starmer held phone conversations with US president Donald Trump and Canadian prime minister
Mark Carney to discuss the possibility of opening the Strait of Hormuz. British finance minister
Rachel Reeves said that the lack of a plan for opening the strait is "frustrating." On 15 March, Trump demanded that
NATO members and China help the US to reopen the strait. On the same day, Japan's Prime Minister
Sanae Takaichi also ruled out any current plans to send
Japanese navy ships to help escort oil tankers through the strait. European Union foreign policy chief
Kaja Kallas said that the EU was exploring the possibility of expanding the scope of its existing naval missions, Aspides and
Atalanta, or establishing a framework for the strait similar to the
Black Sea Grain Initiative. She called for a diplomatic solution to the crisis. Several EU members ruled out military involvement in the crisis: Germany, Italy, Luxembourg, Romania, and the United Kingdom. On 17 March, the Iraqi oil minister said that they are in contact with Iran to negotiate allowing ships to pass. On 19 March, France, Germany, Italy, the Netherlands, the United Kingdom, and Japan announced in a joint statement that they are ready to participate in efforts to reopen the strait. On the same day, a meeting of EU leaders failed to reach an agreement on the subject, with a lack of support for expanding the European Union Naval Force in the Red Sea to cover the strait. The joint statement on securing the strait was joined by other countries by 21 March, including: the UAE, Bahrain, Canada, South Korea, New Zealand, Denmark, Latvia, Slovenia, Estonia, Norway, Sweden, Finland, Czech Republic, Romania, Lithuania, and Australia. On 21 March, UN Secretary General
António Guterres called for the strait to be opened, and suggested that the UN could help secure it. China stated that the war should not have started, and criticised Iran for attacking other countries in the area. On 29 March, Pakistan hosted a meeting with Egypt, Saudi Arabia, and Turkey, to discuss reopening the Strait of Hormuz. On 30 March, Scott Bessent said that the US would gradually "take control" over the Strait of Hormuz. On 30 March, President
Volodymyr Zelensky offered Ukraine's expertise to unblock the strait. Ukraine has managed to keep its ports open by creating a safe corridor through the Black Sea despite constant Russian attacks. Ukrainian strategy includes sharing insurance costs with providers as well as using a combination of armed surface drones, coastal artillery, and air force to repel Russian attacks. On 5 April, French president
Emmanuel Macron and South Korean president
Lee Jae Myung agreed to work together towards opening the Strait of Hormuz. Also on 5 April, the UAE said that it would support a US military operation to take control of the Strait of Hormuz. On 4 April, the vote on Bahrain's proposal at the
UN Security Council calling on states to ensure safety in the strait is uncertain because of divisions among major powers. While many countries support keeping the Strait of Hormuz open for global shipping, countries like Russia and China are concerned the resolution could justify military action near Iran and risk escalation, even though Bahrain had already weakened the proposal by removing stronger language that allowed force. The disagreement remains as Russia and China have veto power. On 7 April, Russia and China vetoed Bahrain's proposal, saying that it was biased against Iran and that it was the wrong message to send after the US president's recent statement threatening the survival of a civilization. Their decision was praised by the Iranian ambassador, and condemned by the US and French ambassadors. On 9 April, UK Foreign Secretary
Yvette Cooper rejected the idea that Iran could charge tolls to ships transiting the Strait. On 10 April, Prime Minister Keir Starmer said that he and President Trump discussed assembling a political and diplomatic coalition for reopening the Strait of Hormuz on a phone call the previous day, and that they also spoke about military options. On 12 April, a UK government spokesperson said that the UK is working with France and others to ensure that ships can pass through the Strait. The next day, French president Emmanuel Macron said that he was organizing a conference with the British to discuss a strategy. On 14 April, French president Emmanuel Macron and British prime minister Keir Starmer announced that they are holding an online meeting on 17 April for countries interested in being involved in a "defensive multilateral mission" to maintaining the Strait of Hormuz open. On 13 April, Admiral
Mark Hammond said that the
Australian navy is ready to open the Strait if the government decides that they should do so. On 16 April, Canada condemned Iran's attacks and said that it is important to keep th eStrait of Hormuz open. While the efforts by the U.S. were occurring to reopen the Straits of Hormuz waterway, China moved to block the
Scarborough Shoal in the South China Sea. On 21 April, during a call with Saudi Crown Prince
Mohammed bin Salman, Chinese leader
Xi Jinping said "The Strait of Hormuz should remain open to normal navigation, which is in the common interest of regional countries and the international community". On 22-23 April, the United Kingdom is hosted a conference of 50 countries about a plan to reopen the Strait. == International law ==
